Duality between k-essence and Rastall gravity
Abstract The k-essence theory with a power-law function of $$(\partial \phi )^2$$ ( ∂ ϕ ) 2 and Rastall’s non-conservative theory of gravity with a scalar field are shown to have the same solutions for the metric under the assumption that both the metric and the scalar fields depend on a single coor...
